Using reverse osmosis filter systems to turn saltwater into freshwater may seem complex, but the reality is that it is actually a simple process to complete. This method is the most trusted for turning nature’s most common resource into a valuable commodity for use in communities throughout the country.
What reverse osmosis removes from the water
Reverse osmosis filter systems remove the dissolved inorganic solids and impurities within water. This process occurs when the water is pushed through a semipermeable filter that is roughly the same thickness as cellophane. This membrane allows the water to pass through, but it traps contaminants such as bacteria, viruses, pesticides, hydrocarbons, and other dissolved solids. The membrane also traps colloidal matter, chlorine, detergents, and industrial wastes. In addition, reverse osmosis filters are also capable of removing dissolved minerals contained within salt water like magnesium, cadmium, sulfates, calcium, and sodium.
In fact, reverse osmosis is more effective at removing material from the water than conventional particle filtration, microfiltration, or nanofiltration. Typically, reverse osmosis will remove up to 94% of sodium, 98% of sulfates, and 98% of phosphate. This efficiency makes water produced by the process healthier and tastier for the consumer.
Components of a reverse osmosis system
The reverse osmosis filter system relies on several components to keep it functioning. The water is first passed through a pre-filter. This filter helps remove sediments and larger contaminants within the water. It is also possible to install a carbon filter that will remove chlorine at this stage. Many treatment facilities using TFC/TFM membranes add a carbon filter because chlorine can prematurely degrade the reverse osmosis membrane.
After the water has been filtered, it is pumped through the reverse osmosis membrane. These membranes are made out of cellulose triacetate. The flow of water is controlled using a flow restrictor that ensures it does not flow too fast or too slow through the membrane. This part of the process ensures that the membrane is able to effectively trap the contaminants. Once the water passes through, it is safe to consume and use for everything from manufacturing to irrigation.
The contaminants are flushed down the drain line, which is connected to the housing containing the reverse osmosis membrane. This step keeps the contaminants out of the freshwater supply and also ensures that they don’t build up and clog the machinery.
As a final step, the water is pumped into a storage tank. From here, it is pumped through a carbon filter that removes any remaining tastes or odors that may still be in the water. Once the water has been filtered and treated, it is pumped into the municipal supply where it makes its way to communities throughout the region.
